Warnings were issued and evacuations were carried out in many countries bordering the Pacific. Its epicenter was underwater, 66 km (41 mi) off the coast of Sendai. The source area of this earthquake has a relatively high coupling coefficient surrounded by areas of relatively low coupling coefficients in the west, north, and south. Source(s): 2011 japanese tsunami place: https://shortly.im/vsr0E. The thousands of bodies, however, exceeded the capacity of available crematoriums and morgues, many of them damaged,[233][234] and there were shortages of both kerosene—each cremation requires 50 litres—and dry ice for preservation. Kyodo News, "Deaths, people missing set to top 1,600: Edano". Aftershocks continued, many exceeding magnitude-7.0. On March 11, 2011, at 2:46 p.m. local time, a magnitude-9.0 earthquake ruptured a 500-kilometer-long fault zone off the northeast coast of Japan. John Rafferty, associate editor of Earth sciences at Encyclopædia Britannica, discussing tsunamis. Furthermore, shortly after the earthquake, some wave meters reported a fluctuation of "20 centimetres (7.9 in)", and this value was broadcast throughout the mass media and the warning system, which caused some residents to underestimate the danger of their situation and even delayed or suspended their evacuation. On 11 March, 2011, a megathrust earthquake struck off the coast of Japan. The north eastern ports of Hachinohe, Sendai, Ishinomaki and Onahama were destroyed, while the Port of Chiba (which serves the hydrocarbon industry) and Japan's ninth-largest container port at Kashima were also affected, though less severely. [260][261][262] Reportedly, some locals had attempted to repair leaks in the dam before it completely failed. Friday’s biggest quake occurred 80 miles offshore and 15.2 miles underwater in a subduction zone called the Japan Trench, part of that plate boundary. Tsunami waves smashed the coast, causing massive damage and flooding. ABOUT THE SHOW. [339][340], Various train services around Japan were also canceled, with JR East suspending all services for the rest of the day. [94] The axial shift was caused by the redistribution of mass on the Earth's surface, which changed the planet's moment of inertia. The GPS station located nearest the epicenter moved almost 4 m (13 ft). Seismic stations in Iwate, Gunma, Saitama and Chiba Prefecture measured a lower 6, recording an upper 5 in Tokyo. Its epicenter was 130 kilometers off Sendai, Honshu; it occurred at a relatively shallow depth of 32 kilometers. An international team of geologists has established the cause of the earthquake and tsunami that hit Japan's Tohoku region in March 2011 and killed over 15,000 people. c. Nuclear Meltdown in 2011 Earthquake in Japan. [269] TEPCO, which normally provides approximately 40 GW of electricity, announced that it could only provide about 30 GW, because 40% of the electricity used in the greater Tokyo area was supplied by reactors in the Niigata and Fukushima prefectures. [57] The Bank of Japan offered ¥15 trillion (US$183 billion) to the banking system on 14 March in an effort to normalize market conditions. [187] Some other South Pacific countries, including Tonga and New Zealand, and US territories American Samoa and Guam, experienced larger-than-normal waves, but did not report any major damage. [395] Gravimetric data from the quake have been used to create a model for increased warning time compared to seismic models, as gravity fields travel faster than seismic waves. Two days of seismic activity made available by the IRIS Consortium were compressed into two minutes of sound. [322], A fire occurred in the turbine section of the Onagawa Nuclear Power Plant following the earthquake. [329], As a result of 7 April aftershock, Onagawa Nuclear Power Plant lost 3 of 4 external power lines and lost cooling function for as much as 80 minutes. Most of these deaths occurred during the first six months after the earthquake and the number dropped thereafter, but as time has passed, the number has continued to increase. The epicenter of the quake was reported to be 129 kilometers (80 miles) off the east coast of the Oshika Peninsula, Tōhoku near Sendai. It was the most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900. Stone monuments at the UNESCO World Heritage Site: Shrines and Temples of Nikkō were toppled. [379] Other nationwide Japanese and international TV networks also broadcast uninterrupted coverage of the disaster. Lv 7. While the Japan Trench was known for creating large quakes, it had not been expected to generate quakes above an 8.0 magnitude. He was killed by the earthquake and tsunami at Kamaishi, Iwate. Seismologists anticipated a very large quake would strike in the same place as the 1923 Great Kantō earthquake — in the Sagami Trough, southwest of Tokyo. [66] Over eight hundred aftershocks of magnitude 4.5 Mw or greater have occurred since the initial quake,[67] including one on 26 October 2013 (local time) of magnitude 7.1 Mw. The tsunami propagated throughout the Pacific Ocean region reaching the entire Pacific coast of North and South America from Alaska to Chile. Director Hideaki Anno's 2016 film Shin Godzilla portrays the titular kaiju as a representation of disasters such as the Tōhoku earthquake and the Fukushima Daiichi nuclear disaster, and criticizes the Japanese government's response to such disasters. [190] Peru reported a wave of 1.5 m (4 ft 11 in) and more than 300 homes damaged. "[386], Nine days after the earthquake hit, a visualization and sonification were uploaded to YouTube allowing listeners to hear the earthquake as it unfolded in time. The backup cooling process is powered by emergency diesel generators at the plants and at Rokkasho nuclear reprocessing plant. [199][200], As of April 2012, wreckage from the tsunami spread around the world, including a soccer ball which was found in Alaska's Middleton Island and a Japanese motorcycle found in British Columbia, Canada. [351] This led to near-paralysis within the capital, with long lines at train stations and many people unable to come to work or get home. The epicentre was located some 80 miles (130 km) east of the city of Sendai, Miyagi prefecture, and the focus occurred at a depth of 18.6 miles (about 30 km) below the floor of the western Pacific Ocean. Articles from Britannica Encyclopedias for elementary and high school students. Its epicenter was 130 kilometers off Sendai, Honshu; it occurred at a relatively shallow depth of 32 kilometers. [338], A tsunami flooded Sendai Airport at 15:55 JST,[134] about 1 hour after the initial quake, causing severe damage. [103], A month later, a major aftershock struck offshore on 7 April with a magnitude of 7.1 Mw. According to some reports, one wave penetrated some 6 miles (10 km) inland after causing the Natori River, which separates Sendai from the city of Natori to the south, to overflow. Around what area did the tsunami take place. 5 Answers. Five million tons of material and debris from Japan were swept out to the Pacific Ocean by the tsunami. The Japan Digital Archive is presented in English and Japanese and is hosted at the Reischauer Institute of Japanese Studies at Harvard University in Cambridge, Massachusetts. Major railways began running trains at 10–20 minute intervals, rather than the usual 3–5 minute intervals, operating some lines only at rush hour and completely shutting down others; notably, the Tōkaidō Main Line, Yokosuka Line, Sōbu Main Line and Chūō-Sōbu Line were all stopped for the day.
